AN INVESTIGATION OF DAMAGE TO THE HUMAN TEMPOROMANDIBULAR JOINT DURING CRANIAL ACCELERATIONS

The literature contains considerable data on the traumatic effects of head-neck acceleration due to rear-end collisions. The temporomandibular (jaw) joint is also subject to indirect loading, due to its inertial behavior. Only a small body of work, Schneider et. al.[1989], describes motion of the mandible in these circumstances. In this study the authors investigate the nature of forces reacted within the temporomandibular joint (TMJ). A model has been built which is a precise representation of the TMJ embodied in a physically exact model cranium. The whole is mounted on an RID-III cervical spine. Sled tests were performed. Results show high angular velocities and accelerations of the mandible for low velocity rear-end impacts.
